HEADLIGHT.

Application fiIed April 14, 1926. Serial N0. 102,016.

This invention relates to improvements in headlights, and has particularreference to headlight adapted to be placed between the customaryheadlights of an automobile so as to give better illumination directlyin front of the car and to the sides thereof in counterrlistinction tothe customary headlights which direct a powerful beam a con siderabledistance away thus leaving a dark spot directly in front of the car andleaving the sides of the road directly adjacent the automobile almostentirely tin-illuminated.

Another object is to produce a light of this character which may be madein a single stamping and one which will be economical to manufacture.

A further object is to produce a lamp which is neat in appearance andone which will not detract from the appearance of the car.

A still further object is to eliminate the necessity of employing a lensfor the purpose of diffusing the light as is common Willi] other lampsof this type.

Other objects and advantages will be apparent during the course of. thefollowing description.

in the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

Figure I is a front elevatio'n of my lamp partly broken away so as toshow the interior thereof,

Figure II is a cross-section taken on the line 2-2 of Figure I,

Figure III is a cross section taken at right angles to that of FigureII, and

Figure IV is a fragmentary perspective view showing the parallelreflecting sun faces.

lit is quite common to have automobile accidents occur due to poorillumination. litany of these accidents occur when cars are rounding acurve. with the result that the driver cannot see any object he may beapproaching.

There are several lamps upon the market at the present time designed toovercome this difficulty. These lamps, however, employ a lens which sodiffuses the light that much of the illumination is lost.

I have therefore produced a light wherein all of the rays are properlycontrolled and directed through a plain piece of glass, thereby securingthe greatest possible illumination where desired.

In the accompanying drawings wherein for the purpose of illustration isshown a preferred example of my invention the numeral 5 designates theshell, which also as shown, forms the body of my headlight. This shellhas a reflecting inner surface and is stamped so as to provide curvedsections 6, 7 and 8. These curved sections are parallel to each other asbest illustrated in Figures I, III and IV.

In these figures, it will also be noted that these parallel portions arecurved from end to end as well as from side to side.

At 9 I have shown an illuminating bulb c: rried in the customary socket11. The bulb has been omitted from Figure III, but shown in dotted linesso as to better illustratc the invention.

Diverging reflecting surfaces are shown at 12 and 13. These divergingsurfaces are secured to the outermost edges of the reflectors 6 and 8.At 14 I have shown a plain glass which is secured to the shell by a rim16 between which shell and glass is positioned a gasket 17.

The result of this construction is that when placed upon the front of anautomobile and properly illuminated as by a bulb 9, the rays of lightcoming from the bulb will strike the parallel reflecting surfaces 6, 7and 8 and will be directed forwardly so as to give a maximum amount ofillumination directly in front of the car upon which the device isinstalled.

At the same time, the reflector surfaces 1% and 13 will reflect some ofthe rays and. direct the same to the sides of the road upon which thevehicle is traveling.

It will thus be seen that I have devised a simple headlight which willaccomplish all of the objects above set forth in an efficient manner.

It is of course obvious that the lamp may be made in sections or stampedas an inte gral unit Without departing from the spirit of the invention.

It is to be understood that the form of my invention herewith to betaken as a preferred example of my invention, and that various changesrelative to the size, shape and arrangement of parts shown and describedis extending transversely of and midway the ends of the body, with asection upon opposite sides of the middle section, curved divergingreflecting surfaces formed upon opposite sides and merging from theouter edges of the outer parallel reflecting sections and cooperatingtherewith so that rays reflected thereby will be directed forwardly in aline with said body and upon opposite sides thereof, a glass carried bysaid body, and a run for securing said glass thereto.

In testimony whereof I afiix my signature.

WILLIAM E. ALLEN.
